What is NA_WorkSheet?

    Na_WorkSheet is a collective aggregation of algorithms coded in Java that
implements various Numerical Analysis solutions/techniques. The worksheet is
generally aimed at educators and students that would like to demonstrate or
analyze various Numerical Analysis methods. The software attempts to provide
a combined execution of algorithms and intermediate data that can be reviewed
and compared.

Features:

• Single variable polynomial equation input for analysis
• Equation graphing.
• Solution and intermediate data output.
• Data retention capacity for comparison.
• Limited input data import for some algorithms.
• (Basic) Formatted print output of worksheet.

Beta New Features:

• Updated polynomial root algorithms.
• Double and triple integration.
• Cubic spline and Bezier interpolation.
• Interpolation point evaluation.
• Matix operations.
• Updated linear systems/decomposition algorithms.
• Equation parser complex number handling.
• (Basic) Formatted print output of worksheet.

Production New Features:

• Recompiles to JRE environment 1.5.
• Rebuild interpolation, matrix operations, and linear systems panels for Linux.
• Update Help Document to Reflect Various Functions That May be used in Equations.
• Update graph interface and scaling capability.
• Modified data import to eliminate CSV separator characters.

Requirements:

• Application - Windows XP, 2000, 95, 98, NT, ME, & Linux, X-Window Environment.
• Java Runtime Environment, JRE 1.4

• Applet - Web Browser IE, Mozilla, Netscape, Opera.

    The NA_WorkSheet can be run as either an applet embedded in a web page
or as a stand alone application. The NA_WorkSheet run as an applet will have
limitations on data import because of security limitations imposed on such Java
runtimes. To get started unzip the release files to your local hard drive.

    Applet:

       1. Copy the included html document "Numerical_WorkSheet.html" to the web
           server directory location desired.
       2. Create the directory structure "/net/danap/numericalworksheet/" within the
           html serving directory from above.
       3. Copy the NumericalWorkSheet.jar file from the release to the /net/danap/
           numericalworksheet/ directory.
       4. Use your browser, IE, Mozilla, to view the Numerical_WorkSheet.html
           document location URL.

    Application:

       1. Change to the directory where the file NumericalWorkSheet.jar was unzipped
           in a command prompt window.
       2. At the command prompt type "java -jar NA_WorkSheet.jar". All aspects of
           the NA_WorkSheet are functional as an application.
       3. A shortcut may be created in the normal way for your platform with the above
           command line and work path associated with the installation directory.
